Fig. 4:.

Referring in detail to the drawings: 1 designates generally a building, for example a garage, having a door opening 2 formed by a frame or casing including an upper cross member or lintel 8, and 4 a swinging door hinged to the casing.

Mounted on the lower face of the lintelis 6 forming-aboss on the exposed face of the plate and a recessbetween the plate and the lintel, and provided with a central aperture 7 adapted to receive a bolt or rivet 8 for roa plat-e 5 having a centrally depressed portion tatably supporting abearingmember 9"from the casing. The bearing member comprises an-elongated channel including a body-1 0 in Whichthe. rivet Sis fixed, spaced flanges or side walls 11, and a transverse arm or bar 12 fixed to one flange and extending across thememberto the otherv flange in an intermediate position,

for slidably retaining a rod 13 having a transverse peripheral notch 14 acent its inner end, adapted to receive the'banfor latching the rod against longitudinal movement in the bearing member. V I I The outer end of the rod is pivotally androtatably'supported by'a bracket l5'securedto the-door, whereby the door will be held open when the bar engagesthe notched portion of therod. p

"The door bracket 15 includes an angle bracket portion 16 fixed to the door. andin eluding a shel f-likefiangev 17 having an aperture 18 to receive a pivot pin l9 mounted in a pivotal .bracket member 20 having bearing openings 1 for rotatably supporting the outer end of the rod.

Thegpivotal bracket member ,20 preferably comprises a web 22 in which the pivot pin is fixed, and spaced flanges 23 having said bearing openings 21 formed substantially centrally therein. A stop member 24 comprising a pin havingopposite'ly projecting ears 25 isgfixed in the rod diametrically opposite the notch 14 .and located between the flanges 23, for engaging the web '22 to limit the rotative movement of the rod.

4 Suspended from the rodpreferably by a loop or strap 26, fixed to the rod-,is a weight 27 adapted to retain theirodin a position in .which its notch is engaged by the bearing member bar, and to return'the rod to latching position. The arms of the strapjspace the weight from the rod, andcomprise a lever 1 whereby the weight, when elevated by rotation of the rod, will tend to move the rod rotatively to latching position.

Attention-is called'to the fact that the weight is in a position on the rod in longi- -'tudinal alignment with the notch 14.

'= An operating member 28 preferably comprising a depending chain" havingone end fixed to the rod is adapted to be wound thereon for rotating the same to release the latching members and permit the rod to slide in the casing bracket for closing the door.

The rod further is preferably tubular and comprises a pipe having a trunnion or shaft portion 29 inserted in its outer end and rotatably mounted in the door bracket. The notch 14 isformed adjacent the inner end of the pipe by slitting the periphery thereof on parallel lines, and depressing the portion between the slits, so that a concave web 30 is depressed into the bore to form rounded bearing edges 31 at opposite sides of the notch.

The shaft 29 is preferably secured to the pipe against rotative and sliding movement y a pin 32 extending through apertures in the pipe and shaft, and having an eye 33 to which the chain is attached. A stop 001- 1211' 34 is fixed to the inner end ofthe pipe, and may comprise an outwardly bent flange on the pi e. 1 I

The weight is fixed to the pipe and normally retains the same in such a position that its notch may engage the bar of the lintel bracket. When the door is opened, the rod is drawn through the bearing member 9, and is stopped by engagement of the rod notch with the barlQ, thus latching the door in open position. I

The rod member is anchored in the door bracket against longitudinal movement, for example by a head on the end of the shaft portion and the shoulder formed by the end of the pipe.

When the door is to be closed, the rod is rotated by means of the hanging chain to move the notched portion away from bar engaging position and thus release the rod so that it may move through the bearing member 9. Rotation of the rod is limited by the stop cars 25, which are adapted to engage the web 22 of the door bracket member 20 when the weight arm extends horizontally and in position to exert maximum lever inadapted to be effective when the rod is in latching position, a weighted arm tending to urge the bar rotatively to latching position, means for rotating the rod to release the latch, and means limiting the rotation of the rod.

4. A door holder including supporting brackets, a rod slidable in one of said brackets, and having pivotal rotative mounting on the other of said brackets, and stop means on said rod including a pin having oppositely projecting ears engageable with one of said brackets for limiting rotative movement thereof.

In testimony, whereof I aifix my signature.

JOSEPH E. HAGSTROM.

finence under the influence of gravity for returning the rod to latching position.

What I claim and desire to secure by Letters Patent is:

1. In a door holder adapted to be applied to a swinging door and a casing, a horizontally'pivotal bearing member mounted on the casing and having a transverse latching bar, a horizontally pivotal bracket mounted on the door, a rotatable rod having one end mounted in the bracket and the other end slidable in said bearing member and provided with a transverse peripheral notch, means operating by gravity to urge the rod into position for engagement of the bar in the notch to latch the rod in open position of the door, and means for rotating the rod to .release the bar and permit the rod to slide in the casing bearing.
